Note: Some of the organizations on the list have since complied with the requirements through their national headquarters. The National Center for Charitable Statistics provided the information, which could have been updated since the list was made public.

The loss of tax-exempt status hit this year because of an IRS law passed in 2006 that requires all non-profit groups to file tax returns at least once within three consecutive years. If they fail to comply, they will lose their exemptions.
